点击表情按钮可以加第一个表情

但是第二次点击表情按钮就不行了

public void onClick(View v) {
// MyDialog myDialog = new MyDialog(MainActivity.this);
// myDialog.show();
dialog =new Dialog(MainActivity.this);
dialog.setContentView(mGridView);
dialog.setTitle("表情选择");
dialog.show();
}
});
感觉问题出在这里， dialog 不是局部的嘛， 为啥每次都去new呢？ dialog.setContentView()这个需要？

The specified child already has a parent. You must call removeView() on the child's parent first

根据提示一个子控件不能有两个parent

问题在这里。
public Drawable getDrawable(String source) {
int id = Integer.parseInt(source);
Drawable draw = getResources().getDrawable(id);
draw.setBounds(0, 0, draw.getIntrinsicWidth(), draw.getIntrinsicHeight());
return draw;
}

[fontlose]

也有可能在这里
dialog =new Dialog(MainActivity.this);
dialog.setContentView(mGridView);
试试重新new个实例加进去

搞定了 dialog没判断 加上
if(dialog!=null) {
dialog.show();
}else {
new ...
}
